The sliding glass door to our patio has been getting harder and harder to open. It’s been on my to-do list for a while, and I had some time today to I took a look at it. After thoroughly cleaning the tracks, and debating popping the door out of the tracks, it was still sticking so much that it took almost all my force to open it. So, I turned to the internet, which in my case means stopping here first.
A quick search turned up this almost 4 year old thread http://boards.straightdope.com/sdmb/showthread.php?t=502301&highlight=%22sliding+door%22
which directed me to a video (link still alive) which answerd my questions. BAM. Door fixed, list item scratched off.
Then, I figured that after poking the zombie with a stick, I should back away to let it sleep and posted in MPSIMS.
Many thanks to all you internet strangers.
